1 Solar-Control Glazing Visionary Façade Concepts

The Age of Glass Glass architecture is the architecture of the 21st century. Glass façades dominate the cities of the world. Glass fires the imagination of designers.

This applies particularly for transparent solar control: astronomical costs for air-conditioning loom in summer and for heating in winter.

However, glazing with colour accents or higher reflectance is experiencing a renaissance in some regions.

2 The Age of Glass Glass architecture is the architecture of the 21st century. Glass façades dominate the cities of the world. Glass fires the imagination of designers. Glass has taken centre stage. But visionary architecture needs high-tech glass. The visual and energy-relevant demands on building envelopes are constantly being raised. This applies particularly for transparent solar control: astronomical costs for air-conditioning loom in summer and for heating in winter. Innovative approaches to control the indoor climate have become imperative! The general trend is toward colour-neutral glazing with a low level of exterior reflection. However, glazing with colour accents or higher reflectance is experiencing a renaissance in some regions. The potential lies in the coating technology: in a complex process, multi-layer coatings are applied to the surface of float glass. Only glass that has been processed in this way has proven to be a multi-purpose, high-quality product that reduces overheating and saves heating energy.

3 The products in the ipasol range represent top-class solar-control glazing. The newest ipasol generation impressively demonstrates the advantages of these products. Whether total solar energy transmittance (g value), light transmittance ( L value) or thermal transmittance (U g value), ipasol offers performance that inspires. At long last, buildings can be optimised to save energy yet still have a glazed exterior and bright interior spaces! The ipasol product range has already proven its structural and optical merits in prestigious major projects around the world. ipasol lowers air-conditioning and heating costs, and captivates by its further optimised appearance. This means total freedom in this age of glass.

Harnessing the Sun The right combination of values The performance of solar-control glazing depends on various parameters such as total solar energy transmittance, light transmittance, thermal

Now that innovative coating processes have established themselves as the state of the art, it is important to find the right combination of technical specifications.

A further criterion is the widespread desire for colour-neutral façade designs. Creative solutions from glass processors are in strong demand.

The latest generation again has very complex coatings that consist of up to 10 individual layers.

4 Harnessing the Sun The right combination of values The performance of solar-control glazing depends on various parameters such as total solar energy transmittance, light transmittance, thermal insulation, transparency and colour neutrality. Now that innovative coating processes have established themselves as the state of the art, it is important to find the right combination of technical specifications. What is the point of having the most effective solar control, if expensive or unpleasant artificial lighting must be used inside the building, or the view to the outside is hindered? A further criterion is the widespread desire for colour-neutral façade designs. Creative solutions from glass processors are in strong demand. Highly selective coatings With its combinations of performance specifications, the ipasol product range often approaches the limits of what is physically feasible. The latest generation again has very complex coatings that consist of up to 10 individual layers. They are all variations of a single principle: The highly selective coatings reflect most of the long-wave solar radiation (lower g value) while transmitting as much short-wave radiation (daylight) as possible (higher L value). Most of the heat remains outside, but not the light. In this way, the ipasol product range can optimally meet the seemingly irreconcilable requirements on modern architectural glazing. ipasol solar-control coating outside inside inert gas spacer bar desiccant butyl primary sealant secondary sealant, e.g. polysulphide / PU Design of an ipasol insulating glazing unit

Firstly, it delays and reduces the heating up of rooms in summer, thus considerably lowering airconditioning costs, which are often much higher than winter heating costs.

Thirdly, ipasol distinguishes itself in winter by the outstanding thermal insulation it provides. It increases the quality of life, preserves the environment and lowers operating costs.

Firstly, it delays and reduces the heating up of rooms in summer, thus considerably lowering airconditioning costs, which are often much higher than winter heating costs. Secondly, ipasol also improves the psychological environment, because bright rooms filled with natural light increase the motivation and productivity of the people working in the building. Thirdly, ipasol distinguishes itself in winter by the outstanding thermal insulation it provides. It increases the quality of life, preserves the environment and lowers operating costs. This also provides a sound financial foundation for visionary architecture. ipacolor - Perfection in detail Often, a façade appears perfectly harmonious only if it is glazed entirely. For completely glazed façades, Interpane offers a finely tuned range of ipacolor spandrel panels, which are perfectly co-ordinated with the ipasol product range. This allows the whole building envelope to be both homogeneous and functional. ipasol spandrel panels are available with single or double glazing, with or without additional thermal insulation. The functional benefits of ipacolor are obvious. ipacolor spandrel panels are: resistant to weathering resistant to environmental influences durable mechanically stable ipasol and ipacolor - a great pair for great façades

6 Also with optimised edge seals its: Warm to the edge As multi-purpose, high-performance glazing, ipasol not only offers excellent solar control but also excellent thermal insulation. However, for future-orientated energysaving strategies, all of the individual components of the solar-control insulating glazing must be examined, e.g. to prevent heat bridges from forming around the edges between the glass and the spacer bar. Consequently, Interpane developed the its thermal spacer system with a special stainless steel profile. Stainless steel has a much lower thermal conductivity than aluminium. It reduces the heat bridges and thus improves the surface temperature at the edge of the glass. This warm edge reduces the linear thermal transmittance coefficient by around 25 %. Structural glazing with gas-impermeable silicone edge sealant outside inside solar-control coating its stainless steel spacer bar Based on the well-proven principle of the metal spacer bar with a dual sealing system, a new type of gasimpermeable edge sealant with silicone as the secondary sealing material was developed. This allows, for example, structural glazing systems to be created that are based on the principle of mounting glazing elements with an exposed edge seal. This high-grade silicone edge sealant system is not only UV-resistant but also allows the cavity between the panes to be filled with argon or krypton, due to its high gas impermeability. Visionary architecture needs futureorientated products. profile of spacer filled with desiccant (molecular sieve) coating removed at the frame edge for reliable sealant bonding silicone sealant for durable bonding to the glass panes and hermetic sealing of the cavity primary sealant, e.g. butyl Design of an ipasol insulating glazing unit with its and silicone edge sealant
